BACKUP STEERING SYSTEM FOR STEER-BY-WIRE HARVESTERS
First Claim
1. A steering system for a harvesting machine, the steering system comprising:
- a steer-by-wire system, comprising;
a first steering mechanism enabling manual steering control of a machine by an operator;
a controller configured by instructions to receive signals based on operator movement of the first steering mechanism and, based on the signals, cause a valve of a hydraulic circuit to control a steering cylinder; and
a backup mechanical steering system, comprising;
a second steering mechanism enabling manual steering control of the machine by the operator, the second steering mechanism mechanically coupled to the valve, the second steering mechanism configured to replace the first steering mechanism based on operator intervention.

15. A steering method for a harvesting machine, the steering method comprising:
-
converting manual movements of a first steering mechanism to electronic signals; causing a valve of a hydraulic circuit to control a steering cylinder based on the electronic signals; and replacing the electronic signals with manual movements of a second steering mechanism, the steering cylinder controlled based on mechanical movements corresponding to the manual movements of the second steering mechanism received at the valve. - View Dependent Claims (16, 17, 18, 19)

20. A non-transitory, computer readable storage medium comprising instructions that, when executed by one or more processors, causes the one or more processors to:
-
convert manual movements of a first steering mechanism to electronic signals; cause a valve of a hydraulic circuit to control a steering cylinder based on the electronic signals; and cause replacement of the electronic signals with manual movements of a second steering mechanism, the steering cylinder controlled based on mechanical movements corresponding to the manual movements of the second steering mechanism received at the valve.
